The temperature at any random location in a kiln used in the manufacture of bricks is normally distributed with a mean of 1000°
Fand a standard deviation of 50° F.
Reference: Ref 2-2
When glazed bricks are put in the oven, they will miscolor if the
temperature is below 900°F. If the bricks are placed randomly
throughout the kiln, the proportion of glazed bricks that miscolor is
closest to
